FN Keys Not Working Properly on ASUS ProArt PX13 in Manjaro

Hi everyone,

I recently bought the ASUS ProArt PX13 and installed Manjaro (latest stable ISO) alongside Windows in a dual-boot setup. Everything is working fine for the most part, but I’ve noticed an issue with the FN keys on the laptop keyboard.

By default, the FN keys (F1-F12) are mapped to media functions (volume, brightness, etc.), but in Manjaro, they don’t work unless I manually hold down the FN key. This is different from my experience on Windows, where the BIOS FN lock setting works correctly—when enabled, the media functions are the default behavior, and F1-F12 require the FN key.

I also use Manjaro on an older laptop and have never encountered this issue before.

Has anyone else faced this issue with ASUS laptops or similar hardware? Are there any logs, configurations, or additional details I should provide to troubleshoot this?

Since this is my first post on the forum, I’d really appreciate any guidance on how to approach this issue properly.

Thanks in advance!
